    Effect of the begomovirus transmission efficiency for the predominance of tomato severe rugose virus (TOSRV) in tomatos crops.

    Tomato severe rugose virus (ToSRV) and Tomato golden vein virus (TGVV) are bipartite begomoviruses, transmitted by whiteflies (Bemisia tabaci biotypeB), frequently found infecting tomato (Solanum lycopersicum) crops in Brazil. To more fully understand the interaction begomovirus/whitefly, as well as how occurrence of mixed infection may influence virus emergence and dominance in an infected plant, a study on begomovirus transmission was carried out focusing on the determination of transmission efficiency of two begomoviruses, ToSRV and TGVV, in single and double infection.Resumo 066
